modelFlowControlled_dpSystem

Demonstration of the use of prescribedPressure

Extends from Modelica.Icons.Example.

Information

This example demonstrates and tests the use of IBPSA.Fluid.Movers.Validation.FlowControlled_dp movers that use parameter prescribeSystemPressure.

The mass flow rates and actual pressure heads of the two configurations are compared.

Parameters

TypeNameDefaultDescription
Modelica.SIunits.MassFlowRatem_flow_nominal0.1Nominal mass flow rate
